I suppose that the question can be understood as a “thought experiment” about the relevance of scales (energy, length or time scales) in the laws of physics as we understand them. In my view, the core question is: “Does the descriptive laws of a system change as one changes the scale at which one observes/probes the physical system?” This is a rightful and ...

I am starting studying quantum mechanics and observed that classical physics ceases to be accurate at the microscopic world. Yes, though there is continuity in physics, the classical fields emerge from the quantum mechanical fields smoothly as numbers of quanta and dimensions grow. My question is if there is a large world so large, when their world is ...

The obvious solution is to add a "dashpot damper" to the mix so that the equation of motion of the surface is $$y''(t) + 2 \lambda ~ y'(t) + \omega^2 y(t) = -\alpha w_0.$$As usual, in this case the equilibrium comes to a height $y_0 = -\alpha w_0 / \omega^2,$ which reads on the scale as the weight $w_0.$ Substituting $y = y_0 + \eta$ gives a function $\eta(... 1 There is the instantaneous force between the mass and the scales, and then there's the reading of the scales. Factors influencing both of these depend on many unknown factors - so here are just some general thoughts. First, if you drop a mass$M$from height$h$onto scales with mass$m\$, and the two will then move as one, the collision is considered ...
